Microcitrus Australasica (finger lime) fruit extract is derived from an Australian citrus and contains natural alpha-hydroxy acids, vitamin C, and other antioxidants. It is used in skincare for mild exfoliation, brightening, and antioxidant protection.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation or stinging | Uncommon | Related to its natural acid (AHA) content, more likely on sensitive skin or at higher concentrations. |
| Redness or transient erythema | Uncommon | Typically mild and resolves after discontinuation or reduced use. |
| Increased photosensitivity | Uncommon | As with AHA-containing products; sunscreen use is advised. |
| Allergic contact dermatitis | Rare | Possible in individuals sensitized to citrus-derived components. |
| Photoallergic or phototoxic reaction | Very rare | Citrus extracts can theoretically contain photoreactive compounds, though purified fruit extracts are generally low risk. |
